Genetically modified crops are plants whose DNA has been altered using biotechnology. This process allows scientists to introduce specific traits, such as resistance to pests or tolerance to herbicides, which can improve crop yields and reduce the need for chemical treatments. Common examples include Bt corn and Roundup Ready soybeans. These modifications can help farmers produce more food while using fewer resources. However, the use of genetically modified organisms (GMOs) is a topic of debate, with concerns about environmental impact, food safety, and biodiversity. Regulatory agencies, like the U.S. Food and Drug Administration, oversee the safety of these crops before they reach consumers.
